By such formation, slit 140a (vortex flow blocking portion 140) blocking utilizes and sends the part that coil 115 is formed at the vortex flow for electric screen 116, by make thus vortex flow a part around, compared with there is no the situation of slit 140a, make the state variation of vortex flow.That is, by making the state variation of vortex flow, the induction coefficient of transmission coil 115 being changed, making this induction coefficient be the suitableeest induction coefficient mated with the receiving coil 126 by motor 125.Especially owing to making the two ends of slit 140a lay respectively at outside relative to the two ends in coil axes (central shaft) direction sending coil 115, therefore, more blocking be formed at for electric screen 116 vortex flow and around, thus, the state of vortex flow is changed larger, utilizes receiving coil 126 to mate.
In addition, by motor 125, also there is the structure roughly the same with the power supply machine 114 shown in Fig. 2 A, in cabinet (not shown), possess receiving coil 126, by electric screen 127 (electroconductive component), by panel for electric conductor 128.Further, in the configuration of the side of receiving coil 126 by electric screen 127, in opposite side configuration by panel for electric conductor 128.These, by electric screen 127, parallel with the coil axes of receiving coil 126 by panel for electric conductor 128, configure opposedly with receiving coil 126.But, identical with power supply conductor plate 117, also can omit by panel for electric conductor 128.
In addition, relative to receiving coil 126, the opposition side of the side opposed with sending coil 115, and be configured near receiving coil 126 by electric screen 127, identical with for electric screen 116, form the vortex flow blocking portion 140 formed by slit 140a.Thus, the induction coefficient of receiving coil 126 also changes, and this induction coefficient is the suitableeest induction coefficient mated with the transmission coil 115 of power supply machine 114.
At this, form the slit 140a in vortex flow blocking portion 140 as shown in Figure 2 B, multiple parallel to each other to make, and to be formed roughly at equal intervals, and extending along the direction of the coil axes (central shaft) sending coil 115 (or receiving coil 126), the mode that its two ends lay respectively at outside relative to the two ends sending coil 115 (or receiving coil 126) is formed.Slit 140a interdict vortex flow a part and make above-mentioned vortex flow around, as long as the state variation of vortex flow can be made compared with not having the occasion of slit 140a, then can adopt various ways.
Specifically, for the quantity of slit 140a, can be one or individual arbitrarily, in addition, its width, length also suitably set according to the shape etc. sending coil 115 or receiving coil 126.When forming multiple slit 140a, its width, length also can not be made all to change width or length respectively in the same manner.In addition, can a slit 140a shown in Fig. 2 B be divided into multiple, in this case, also can change width, the length of the slit after segmentation.In addition, for the configuration of the slit after segmentation, can be regular, also can be irregular.In addition, in order to change the degree of depth of slit, can change and be formed for electric screen 116, thickness by the conductive plate of electric screen 127.
In addition, as making the form that slit 140a is extremely short, can only form hole and using the structural element of this hole as vortex flow blocking portion 140.In this case, quantity, the configuration in hole are also arbitrary, can send the direction arrangement of the coil axes (central shaft) of coil 115 (or receiving coil 126), such as, be configured to zigzag at the length direction of slit 140a, i.e. edge.In addition, can configure brokenly, also can make part rule and remainder is configured brokenly.
Then, to possess be formed this vortex flow blocking portion 140 for electric screen 116 or by electric screen 127, power supply machine 114 or the manufacture method by motor 125 be described.
First, as electric screen 116, by electric screen 127 electroconductive component, prepare the conductive plates such as multiple copper coins respectively.
Then, form vortex flow blocking portion 140 respectively relative to these multiple conductive plates, formed as the confession electric screen 116 of processing electrically conductive parts, by electric screen 127.But, multiple conductive plate is changed to the form in the vortex flow blocking portion 140 formed respectively, forms multiple processing electrically conductive parts (for electric screen 116, by electric screen 127) thus.Specifically, between conductive plate, change quantity, the width of slit as mentioned above, or its width, length are changed to the multiple slits being formed at identical conductive plate.In addition, part or all of slit is changed into hole.In addition, by preparing the different conductive plate of thickness in advance, change the degree of depth of slit.
